VC-1 vs XVid

I have some XVid videos that I want to convert to WMV VC-1 Main as they are more compatible with my XBOX. Don't want a war about using one or the other and you can use both. What I'm curious about, is if I have a 604 x 256 XVID encoded at 700 and some kbps what would you think in theory I would need to encode a WMV at to limit picture loss? Maybe 10% more?

Thanks.

JR

Why don't you use your original DVDs as a source? Xvid @700 Kbps and 604 x 256 is as bad as it gets.

I can't. This was one of those, hey I got my new Costco CD shreader and converted a bunch of originals to electronic as part of a closet cleanout and no longer have any of my originals. Unless I can find all the bits and pieces and glue them back together.

Your Xbox 360 should be able to play MPEG-4 ASP encoded content without issue.

I think he's referring to an original XBOX. Still, it should handle low res MPEG-4 ASP without issue!!

And if you're reencoding from that low a bitrate, definitely make sure you've got a deblocking decoder being used as input!

But yeah, the files should play as is, certainly on the 360.
